This `invention relates te closure devices and, more particularly, to a door havingnovel ime'a'ns thereon for Y mounting the same within a frame.

The prlmary object lof the instant' invention is to provide a door having hinge means on one edge `thereof adapting the same to be mounted within a frame with the edge dlsposed in proximate oppositionto the outertes Patenti most -face of the frame jamb, the door edge land lhinges being constructed so that the leaf of the hinge adapte for attachment to the jamb may be placed on the jamb in a flush, unmortised position while allowing 'the door to be 4completely swung to its normally closed location within the frame. V An equally impor-'tant 'object ofthe instant invention is to provide door structure as referred. to above wherein the 'leaf of the hinge attached to the edge of the door is received within a recess in the edge Iof sufcientgdepth to receive both of the hinge leaves 'therewithinwhen the door is swung to its closed position within the frame'.

A further important object of this invention is to 'provide such door structure wherein a U-shaped channel is attached to one extremity of the door and wherein the recess for receiving the leaf of the hinge is press-formed into the bight of the channel thereby materially lessening the cost of production and making the channel member universally adaptable for any size doors.

Also another important object of this invention is to provide the type of door structure which has lbeen referred to above wherein the bight of the channel isbeveled so that a close iit of the channel against the ja'rnb of the frame is obtained irrespective of slight misalignment of the hinge leaf when the same is placed on the jamb.

Other objects will appear vhereinafter or become obviou as the following specification progresses.

In the drawing:

Figure 1 is a fragmentary, front elevational view of door structure embodying the concepts of the instant invention and showing the same'disposed Within a suitable frame.

Fig. 2 is a fragmentary, perspective view illustrating a door attached to the frame and situated in an open position.

Fig. 3 is an enlarged, fragmentary, cross-sectional view taken on line III--lll of Fig. l; and

Fig. 4 is an enlarged, fragmentary, cross-sectional view taken on line IV-IV of Fig. l.

A closure device designated broadly by the numeral 10 is illustrated fragmentarily in Fig. l of the drawing and it can be seen therein that a rectangular door 12 is adapted for pivotal mounting within a frame 14 in a manner to be hereinafter described. Frame 14 has a Samb 16 which in turn has an outermost face 18.

Door 12 may be of the conventional type wherein a screen panel 20 is removably mounted therein so that other types of panels may be placed therein such as glass panes or the like in order to convert door 14 to a stormtype closure device. As can be ascertained from the Patented Mar. l, 195) 2 v drawings, the longitudinal vlength of door l12 is substantially equal to the distance between crosspieces 22 and 24 of frame 14, but the transverse vwidth of the door '112 i's somewhat 'less than the width `between ljainb 16 andthe other vertical frarnepiece (not shown), this being illustrated in Figs. 3 and y4.

Mounted on the longitudinal extremity 26 of door i2 is an elongated U-shaped channel 28 which has a pair of spaced, parallel legs 30 and 32 anda transverse bight v34. 'Channel 2S is adapted to be mounted on extremity 26 of door 12 by virtue of the fact vthat legs '30 and 32 are spaced a distance slightly greater than the width of extremity 26 and, therefore, the extremity 26 extends be- `tween legs 3 0 and 32 in engagement with the `iu'ne'rt'n'ost faces thereof, it being manifest that channel 28 is co- Yextensive in length with the longitudinal dimension of door 12. Means for securing channel 28 to door 12 may take any convenient form, but a plurality of screws 36 are desirable.

From the foregoing it can be appreciated that when channel 28 is disposed on door 12, there is a slight distance between extremity 26 and bight 34 of channel 28 lfor reasons hereinafter to be explained. Also, because of the construction as above outlined, it 'can be perceived that, by virtue of the provision of channel 28, door -1'2 `.can be made to t openings of various widths 'by securing channel 28 to door 12 with the extremity 26 extending between legs 30 and 32 for a distance sufficient to cause vthe external dimensions of the door tort the desired opening. In other words, by moving channel 28 outwardly and inwardly with respect to the 'extremity or-edge 26-of door 12, the transverse Width of door .12 may be varied to t a particular opening.

Structure for pivotally mounting door 12 withinfrarne 14 may conveniently consist of a 'pair of hinges Vsuchas 38 each of the hinges 38 including a door leaf 40 and a jamb leaf 42 which are pivotally interconnected in the vconventional manner by a pin 44 extending through axially aligned bores 46 forming a part of the leaves.

In Fig. 2 the manner of attaching hinge 3'8 to door 12 and jamb 16 is illustrated and it can be seen that door leaf 40 is attached to bight 34 by suitable means such as :rivets 4S while jarnb leaf 42 is attached to the face 18 of Vjamb 16 by a plurality of screws S0. v

Closure device 10 is adapted to be mounted within frame 12 in such a manner that the jamb leaves 42 of hinge 38 need not be mortised into the face 18 of jamb 16 and, as clearly illustrated in Fig. 2, the door leaf 42 is disposed in a flush unmortised position on face 18. Thus, when jamb leaf 42 is attached to face 18 it can be seen that when door 12 is moved to a position within frame 14, bight 34 and face 18 are located in proximate opposition. However, it is manifest that inasmuch as jamb leaf 42 is disposed in an unrnortised position, that complete closing of'door 12 within the frame 14 would be precluded because of engagement with door leaf 4). Therefore, door leaf 40 is mounted within a recess 52 in channel 28, it being manifest that recess 52 must be of suiicient depth that both of the leaves 40 and 42 are disposed therewithin when door 12 is swung into position within frame 14. In this respect it is pointed out that inasmuch as channel 28 has a bight 34, the recess 52 may be conveniently constructed by press-forming inwardly an area S4 of bight 34- complemental to the length of door leaf 40. 4

For reasons to be hereinafter set forth, it is preferable that the bight 34 present a beveled surface 56 and'thus it can be seen that the zone of juncture 58 between bight 34 and leg 30 is located in a position longitudinally offset inwardly fromthe zone of juncture 60 between leg 32 and bight 34. From the foregoing it can be seen that the beveled surface 56 extends inwardly toward door 12 3 from the point of pivotal interconnection provided by pin 44 of hinge 38.

By virtue of the provision of bevelel surface 56 on channel 28, it can be appreciated that door 12 will swing into a position within frame 14 with the edge 58 of channel 28 disposed adjacent face 18 of jamb 16 irrespective of the fact that hinge 38 may not be perfectly installed on face 18 or door 12, or if the door sill is not at a perfect right-angle with respect to the outermost face of door 12.

Because of the fact that the bight of channel 28 is beveled, it can be appreciated that area 54 need be pressformed inwardly only a sucient distance to receive both leaves 40 and 42 thcrewithin and in this respect it has been found that if channel 28 is beveled substantially at an angle as shown in Fig. 4, that area 54 need only be press-formed inwardly so that the same lies in a plane that passes through the zone of juncture 60 and is substantially perpendicular to a plane passing through leg 32.

It should be noted that by virtue of the beveling of bight 34 to present surface 56, the ease of producing recesses 52 in channel 28 is greatly increased with the cost of production of the door assembly 16 being materially lessened as well as reducing the amounts and types of machinery necessary to manufacture the units. This is true becauseof the fact that channel 28 is U-shaped and the latter may be produced by subjecting a sheet of metal to the action of a die in a stamping machine, such die being suitably conformed to also at the same time, produce recesses 52. Therefore, since bight 34 is beveled, the action of the die in forming recesses 52, produces a peened or outwardly extending, crimped segment 58 on the face 30 of channel 28, thus precluding any tendency of the metal to peen or extend outwardly from the face 32 of channel 28 which would interfere with the ilush engagement of face 32 with the frame 14. In other words, because the force of the die is against a beveled surface such as 56, the force vector produced causes the metal to be moved to a position as indicated in Fig. 4 and the zone of juncture 60 presents a smooth surface, thereby precluding any crimping as occurson the opposite edge of channel 28.

Having thus described the invention what is claimed as new and desired to be secured by Letters Patent is:
